Lee pulled ahead in Game Three, staging a surprise reversal after Gu led for most of the game. Gu, playing white, made a small overplay in the late middle game, invading black’s position at the top with move 146. Lee met this with unrelenting force and an iron will. He managed to kill all of white’s invading stones, bringing himself back into the game and going on to win by half a point.

Game Four was the most complicated of the series, opening with a new and fiendishly difficult variation in the lower right. The fighting spread from there and didn’t stop for the whole game. Many assumed the game was over and that Lee had won the title when he took a decided advantage at move 134. However, Gu kept fighting and pulled off an even more amazing reversal with his brilliant play from move 173 onwards. Be sure to check out An Younggil 8P’s commentary.

Given the preceding games, there was a lot of excitement around the fifth and final match. The game itself was relatively peaceful and, unfortunately for Gu, Lee took the lead after Gu misjudged a ko around move 70. After this, Lee demonstrated how to win a won game, trading his way around Gu’s strong challenges and leading things into the endgame. Gu resigned after all his opportunities to reverse the game had been eliminated, giving Lee Sedol his second consecutive win in the BC Card Cup. This also resolves the deadlock in the head-to-head record between these players, with the record now tilting in Lee’s favor at 14-13.
